Home lab? Yes, first steps taken! This has been in my mind for some time. Why? First for learning purposes but it has potential for more in the future. Home network lab is not a same thing than large corporate network with multiple inter-connected sites, but it is a good start, anyway!

Home lab gives me an opportunity to get my hands on real stuff to see a blink of the physical side of network planning, giving more perspective for the whole process rather than only playing with logical (or virtually simulated) network topologies in network simulation software.
